About

The innovative science behind our patented technology was developed and patented by Dr. Jozef Zwislocki, distinguished Professor of Neuroscience Emeritus and founder of the Institute for Sensory Research at Syracuse University.

Soft ear cuffs form a seal at the outer ear canal. The SensGard chamber then acts as an extension of the ear canal, creating one long tube from your inner ear to the end of the chamber.

Sound energy will travel a path of least resistance, flowing away from the sensitive inner ear and into the low pressure chamber.

Intelligent Solutions for Safe Hearing

Dr. Zwislocki tuned the chamber to achieve a high reduction in sound, spread evenly across all frequencies from low to high. That's why musicians use the SensGard Ear Muffler. All sounds are natural and undistorted, just reduced to a safe volume.

Low frequency noise is reduced as much as the high frequencies. But low frequency noise masks the speech frequencies. Have you ever been to a crowded diner, with plates clanking, fans humming, appliances running and it is difficult to hear conversation? That is low frequency noise masking the speech frequencies. By significantly reducing the low volume noise, speech can be heard clearly.

So you can use your SensGard Ear Muffler around loud noise and hear the person next to you, without the need to remove your protection. Isn't that the way it should work? Go ahead and ask our customers. It is what they like most about our ear muffler.
